ABB Error 50204 — Motion supervision triggered
WarningABB 50204 (“Motion supervision triggered”): The model-based supervision (position/speed/torque coherence) tripped.
Updated 2026-09-17 · LogrobotLM reference
What it means
The model-based supervision (position/speed/torque coherence) tripped. Same investigation logic as a collision, plus tuning: an under-declared payload is the classic false trigger.
What to check
- Confirm payload and center of gravity of the tool + part actually carried.
- Check for process forces (pressing, rubbing) not modeled in the move.
- Only then consider raising supervision levels — never mask a mechanical symptom.

Indicative field information — the robot manufacturer's manual and safety procedures always prevail. Never bypass a safety device; apply lockout/tagout (LOTO) before any physical intervention. How this reference is built →
